Effectively disabling power management all together. So (if I understand correctly) to put it simply power management just doesn't work on my board, right? If you have any suggestion / thing you'd like me to try / thing you want to know please tell me, since power management was really the only thing holding me to the proprietary drivers... -- Configure bugmail: http://bugs.freedesktop.org/userprefs.cgi?tab=email --- You are receiving this mail because: --- You are the assignee for the bug. ___ xorg-driver-ati mailing list xorg-driver-ati@lists.x.org http://lists.x.org/mailman/listinfo/xorg-driver-ati

ClockGating - Enables chips specific power saving features like clock gating that are handled by the hardware directly. This doesn't really do much on r6xx/r7xx boards yet. 2. DynamicPM - Automatically reduces the engine clock and pcie lanes when dpms has powered down the displays 3. ForceLowPowerMode - Runs the chip at a constant reduced engine clock and pcie lanes. -- Configure bugmail: http://bugs.freedesktop.org/userprefs.cgi?tab=email --- You are receiving this mail because: --- You are the assignee for the bug. ___ xorg-driver-ati mailing list xorg-driver-ati@lists.x.org http://lists.x.org/mailman/listinfo/xorg-driver-ati

http://bugs.freedesktop.org/show_bug.cgi?id=21452 --- Comment #3 from Stefano Carignano 2009-05-20 04:59:36 PST --- Okay, looking around a bit I found a quick workaround: from the irc log http://www.radeonhd.org/?page=archive_display&c=radeon&m=4&y=2009&d=2009-4-15 I have read: tormod: agd5f: ok it helped. now X starts, but the laptop freezes solid when I switch VT agd5f: tormod: comment out the RADEONSetClockGating() calls in RADEONPMEnterVT() and RADEONPMLeaveVT() and RADEONPMFini() agd5f: in radeon_pm.c tormod: thanks agd5f: tormod: I'll commit a fix I found that those three lines actually were not commented in current git code, so I commented them and now I can switch back to console / shutdown the system properly. Whether removing those lines is dangerous (and that's why agd5f hasn't removed them yet) or it is the right way to do it, I really have no idea. -- Configure bugmail: http://bugs.freedesktop.org/userprefs.cgi?tab=email --- You are receiving this mail because: --- You are the assignee for the bug. ___ xorg-driver-ati mailing list xorg-driver-ati@lists.x.org http://lists.x.org/mailman/listinfo/xorg-driver-ati
